' ATTACHMENT FQR SAW -GINS- SPECIFICATION forming part of Letters PatentNo. 778,071, dated December 20, 1904. Application filed June 11,1904.Serial No. 212,156.

T (1, whom it may concern.-

Be it'known that I, STEPHEN W. POWER, a citizen of the United States,residing at Murfreesboro, in the county of Pike and State of ,Arkansas,have invented a new and useful Attachment for Saw-Grins, of which thefollowing is a specification.

This invention relates to attachments to cotton-gins for removingadhering material from the saws of the same, and has for its object toprovide a simply constructed. and efiicient device which may be adjustedrelative to the brush-cylinder to cause the latter to act with increasedforce upon the teeth of the gin-saws and remove adhering particlestherefrom. Another object of the invention is to produce asimply-constructed and easily-applied device which serves the twofoldpurpose of a partition or stop member between the ginsaws and as a meanswhereby theadhering particles are removed from the same. With these andother objects in view, which will appear as the nature of the inventionis better understood, the same consists in certain novel features ofconstruction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation, it

1 being understood that the invention is not necessarily limitedthereto, as various changes in the shape, proportions, and generalassemblage of the parts maybe resorted to-without departing from theprinciple of the invention or sacrificing any of its advantages, and theright is therefore reserved of making all the changes and modificationswhich fairly fall within the scope of. the invention and the claims madetherefor.

In the drawings thus employed, Figure 1 is a transverse sectionalelevation of a portion of a cotton-gin including the gin-saws andbrushcylinder with the improved device applied. Fig. 2 is afrontelevation with the brush-cylinder removed. Fig. 3 is a perspective viewof the improved device detached. Fig. 4 is a sectional plan view, drawnto an enlarged scale,

illustrating the contour in cross-section of the brush -defiecting meansand their position with respect to the saw and brushes. The improveddevice may be attached to any of the various constructions ofcotton-gins and similar devices manufactured by making slight andimmaterial modifications in the means of connecting the same, but forthe purpose of illustration is shown applied to a conventional form ofcotton-gin, in which the supportingframe 10, gin-saws 11, mounted on ashaft 12 and separated by the spacer-disks 13, brushcylinder 14:, andbreast-ribs 15 are shown in the usual form and in the usual relativepositions. The improved attachment comprises a head member (representedas a whole at 16) comprising two plates 17 18, connected togetherlongitudinally and with longitudinal grooves in the opposite edges ofthe plate 17 one to receive a rod 19, with its ends 20 21 extendedthrough bearings in the opposite sides of the frame 10, and the othergroove to re into a crank 24 to enable the rod to be rocked in itsbearings in the frame to swing the head 16 to cause the ribs 22 to bemoved toward or away from the brush-cylinder, as required.

Some means, such as a set-screw 25, will be employed to hold the rod andits attached head and ribs in any required position.

The widths of the ribs 22 will be suflicient to closely engage the sidesof the gin-saws and will present relatively sharp edges constantly tothe same, as will be obvious, so that particles of material will beprevented from adhering to the saws. The ribs when thus supported servethe purpose of thepartition ordinarily employed in gins; but in event ofthe gumming of the saws, as when operating on damp cotton, by simplyadjusting the rod 19 by means of the crank 24 the ribs can be forciblymoved toward and in contact with the brush members, With the efiect ofdistending the bristles laterally and causing them to be forciblycompressed against the saw-teeth and by thus concentrating the action ofthe bristles of the saws effectually remove all adhering particles. Thusthe gin-saws can be very easily cleaned While the machine is running andas often as required and when operating upon dry cotton, which does notgum the saws, the device can be secured in position to serve only as aguard or partition, as above noted.

The device is very simple in construction, may be inexpensivelymanufactured, and can be readily applied to any of the various forms ofcotton-gins manufactured and will be found very eflicient for thepurposes denoted.

The parts may be of any suitable material and of any suitableproportions to adapt them to the work required.

Having thus described the invention, what I claim is- 1. In acotton-gin, the combination with the saws and brush-cylinder, of meansfor concentrating the action of the brushes on the saws.

2. In a cotton-gin, the combination with the saws and brush-cylinder, ofmeans for defleeting the brush-bristles into contact with the saws.

3. In acotton-gin, the combination with the saws and brush-cylinder, ofa plurality of spaced ribs arranged between the saws and having inclinedfaces for deflecting the brushbristles into contact with the saws.

4C. In a cotton-gin, the combination with the saws and brush-cylinder,of a plurality of ribs \I-shaped in cross-section and extending betweensaid saws, said ribs serving to deflect the brush-bristles into contactwith the saws.

5. In acotton-gin, the combination with the saws and brush-cylinder, ofa plurality of spaced ribs extending between the saws and, adjustable toa position to coact with said brush in cleaning the saws.

6. In a cotton-gin, the combination with the saws and brush-cylinder, ofa plurality o l ribs having angular faces for contact with the brushes,and means for adjusting said ribs from and toward the brush-cylimler.

7. In acotton-gin, the combination with the saws and brush-cylinder, ofa Avotally-mounted frame, a plurality of ribs carried thereby andextending between the saws, and means for adjusting the position of theframe and ribs to move the latter ribs into and out of operativerelation with the brush-0y]inder.

8. In acotton-gin, the combination with the saws and brush-cylimler, ofa head member formed of a pair of rigidly-united plates, one of saidplates having longitudinal grooves in its opposite edges, a pivot-rodsecured in one of the grooves, and a plurality of ribs secured in theother of such grooves and spaced apart for entrance between the saws,the head member being adjustable on its pivot-rod to alter the relativepositions of the ribs with respect to the brush-cylinder.

In testimony that I claim the 'loregoing as my own I have hereto allixedmy signature in the presence of two witnesses.

STEPHEN \V. IOYVER.
